The mounts are a piece of aluminum plate with going between the window track and the door trim strip. I installed a piece of plastic about 3/8" think on the back side. It covers all of the area except where it mounts to the door trim. This also makes it align properly. I screwed the bracket into the door trim and window track. The mirror is modified slightly shortening the mounting stubs and the plastic on the mounting sheet counter sunk. I will post a picture at the end of next week when I get back to AZ.

Engineering students, help a fellow student out.
SHO-Z replied to xxjoeyxxeb's topic in Non Tech Board
Every thing from math, eng econ, fluids, thermo, statics, dynamics, heat transfer, machine design, material science and ETC. It covers all of your eng. classes. Look in your book store to get an idea. There are some on half.com starting at around $6 plus shipping. -

One book for all of you Mech Eng students out there that helped me get through school was "Mechanical Engineering Reference Manual" by Linbeburg, also get the solution manual. I really simplifies the subjects. You will need it anyway for studying for you PE down the road. -
I got these off of Ebay carbonfiber look, made brackets out of aluminum plate and 1/2" plastic sheet.

I am doing a weber blow through using an Eaton M62, 1 liter disp. With a 2.5 ratio I calculate at 11.5 psi of boost. With the flow losses it will most likely be about 10 PSI or less at the carbs. Look up the efficiency of the supercharger to find out how much pressure is lost due to blow by. The intercooler and piping will also cause pressure loss. I am not looking at high RPM power 4 to 5 grand is about as high of an RPM that I plan on rapping the thing.

Calc For Roots type of Superchargers ((Super Charger Disp X Pulley Ratio X 14.7)/ (½ Engine Displacement)) - 14.7= Boost Pressure

If this is not your daily driver, get the collector car insurance and go license it, you do not need to pass the emissions test in AZ. There is a post on the Desert Z Club web site that a guy with late model 300ZX that did this.

I just said forget it, my 260z wouldn't pass at idle no matter what, high HC. When AZ passed the collector car exemption on passing emissions, I got Hagerty Insurance on the Z, took my insurance papers to DMV and got my plates. As far a being burned out on having my Z, I think of getting rid of it about once a week. I really do not drive it that much, I have put maybe 500 miles on it in the last 6 years and is just taking up space in the garage. Then I think about what I would do if I didn’t have it to tinker with, of course that will all stop when the temps go the HELLAZONA range. Of course I will not be driving the car either at those temps. I did find out that weak spark will cause High HC, one of these days I am going to put a MSD multi spark on the Z.

Question on " a plug " near left hand head
SHO-Z replied to gretchen/jason's topic in Gen I & II Chevy V8 Tech Board
It could be the Knock senor connection. It has been a long time since I was around a Chevy Small Block. -
This might get you part of the way Kennedy Adapters makes attapter plates and fly wheels for the 2.7 Subie engine. I would contact them. http://www.kennedyeng.com/vw_por.htm

It looks like the exhaust is only tacked together. I can imagine all of the fun having to do all of those fusion tig welds. I worked as a pipe welder on a couple of Bud Breweries. It will take a planning on were to start and finish. I should not be surprised at the exhaust header being so well designed after seeing your intake. When are you going to take us into the mystical world of what you are doing with the engine. Desometric valve system, titanium rods, ceramic pistons who knows what you will come up with!

How about a 944 Porsche trans, they can handle a chevy V8. Use the suspension off of a factory 5 cobra on the front end and large flares all around.

Use Dunz aircraft fasteners they look better and will not scratch the paint.

It is going to be interesting to see the HP gain with this set up especially if a stock manifold is used a base line and then changed out for this set up. It makes us low budget people green with envy. Every time I see this tread I cannot wait to see what is happening next, keep it up! "Some people do have brains and money!"

One thing that I have found in my research is that you have to have more air pressure in the floats than in carbs. Here is a picture of my box and vent tubing for the floats. The HSK intake has baffels to increase the float pressure. These are SK Racing carbs. My set up is using a supercharger in lieu of a trubo. I figure that I will loose about 1 PSI of boost through the intercooler and piping. I will be running a stock Subaru WRX intercooler, it should take care of 10 psi of boost. So will have to bleed off some of the excess pressure to the floats.
-
I was looking at the flow pattern and at the front of the box and carb #1. It looks like a diffuser plate just inside of the box would improve air to the first carb. I mocked up one out of 3/4" copper pipe that is split apart and will be silfossing back together and is about 1-1/2" across. This would cause turbulence in the front of the box and would force air to carb #1.

D.O.T. requires red reflectors on the rear of all cars, any cop in the country can pull you over and ticket you, and quite possibly have your car towed away. What looks neat is not alway legal!!

You can form some types Plexiglas by heating in an oven and laying it over a mold. The mold need to be perfectly smooth, the plastic will pick up any imperfection. I think you idea looks neat but needs to be functional ie brake cooling ducts.

When I got my SK Racing, weber clones, who ever ran them last did not drain them. All of the jets were plugged and bowls were full of hard jelled gas residue. It took days to get them cleaned out. I used a tip cleaner for a welding troche to clean the jets. Even if the bowls are clean your jets could be plugged. I would pull all of the jets and clean them.

URGENT: Z broke down on road trip today - electrical issue?
SHO-Z replied to PhilbertZ's topic in S130 Series - 280ZX
My 240z, 280z and 87 4runner had brushes, changed them out and saved a bunch on instead of buying a rebuild alternator. -
Old school shade tree check. Start you engine and let it idle pull one plug wire at a time. If the knock goes way on you have a bad rod on that cylinder. A cracked piston can also be check this way.

Mechanical Engineering vs Mechanical Engineering Technology
SHO-Z replied to Pete84's topic in Non Tech Board
Say what everyone wants about the MET degree at MSCD. It has all real engineers teaching classes, no grad students. When I went there they all had experience in the real world and every one was a PE. Doesn't Cal Poly San Louis Obispo also have a MET degree? -
Mechanical Engineering vs Mechanical Engineering Technology
SHO-Z replied to Pete84's topic in Non Tech Board
It really matters what industry you want you career to be in. HVAC design, firms that design and build projects, Petrochem, and the like you might start on a CAD station to learn the design aspect of the industry, and then move on to engineering just like the ME sitting next to you, it is a training tool to learn the industry. When you graduate you have the skills of and engineer, but not the skills of the particular industry that you will be working in. I would not be effective working machine design or high tech or aviation and engineers from those industries would not be effective in mine. We all specialize after graduation. If I was young and have all of the skills and time to get through an ME program I would do that. When I started my MET program it was I had not ever taken and algebra class. I was on workman’s Comp due to a back injury and need a career change. Over half of the students were older, coming from various industries, from high tech to HVAC. Look where you want to be in 10 years after graduation, then make your decision. MET will get you as far as you want to go in some industries and not in others. ME will get you in all industries to the limit that at Masters is not required. Do not knock the CAD designers, experienced pipers are making about $60 / hr and working about all of the time and a half overtime they want in the Petrochemical industry. -
Mechanical Engineering vs Mechanical Engineering Technology
SHO-Z replied to Pete84's topic in Non Tech Board
I have an MET degree out of Metropolitan State College of Denver. Very basically I did not have to take Calc III or Differential Equations and my Physics was Algebra based not Calc based, all of the other classes where the same as CSU and we used a lot of the same books. I had to wait until I graduated to take the State Engineer in Training Exam, ME can take it in there senior year. I also had to wait and extra year to take my PE. If you are planning on getting a masters degree go ME. I have been employed as a Piping Engineer, Mechanical Design Engineer, and now a Field Mechanical Engineer in the oil fields. Check and see if your program is ABET accredited, what the state requirements in your state are for taking the PE exam. If you have a PE no one cares if you have a ME or MET. I was in my 40s and had a back injury and had to change occupations and went for the MET degree. Most engineering design from what I see will hire you with a MET, and there are those who only think a ME will do. I have never used Calc since I graduated. The PE exam is all algebra based. My best professor put it like this “As Engineers we add, subtract, multiply and divide, look it up in the right book and know our answer makes sense, and can explain to someone else what we did.” -
